.SH DESCRIPTION
The \fBddi_no_info()\fR function always returns \fBDDI_FAILURE\fR. It is
provided as a convenience routine for drivers not providing a \fBcb_ops\fR(9S)
or for network drivers only providing DLPI-2 services. Such drivers can use
\fBddi_no_info()\fR in the \fBdevo_getinfo\fR entry point (see
\fBgetinfo\fR(9E)) of the \fBdev_ops\fR(9S) structure.
.SH RETURN VALUES
The \fBddi_no_info()\fR function always returns \fBDDI_FAILURE\fR.
